IMPROVEMENT lN STEAM-TRAPS.

Specification forming part of Letters Patent No. 125,459, dated April 9,1872.

To all persons to whom these presents may come:

Be it known that I, Onnrsrornnn Kan- MERER, of Boston, of the county ofSufl'olk State of Massachusetts, have invented a new and usefulImprovement in Steam-Traps; and do hereby declare the same to be fullydescribed in the following specification and represented in theaccompanying drawing, of which- Figure l is a vertical and longitudinalsection of my improved steam-trap. Fig. 2 is a horizontal section takenthrough its eductioncoc The nature of my invention or improvementconsists in a hollow float open at top, a tubular arm and adischarge-cock, arranged and combined together, and with a closed casein manner, and so as to operate essentially as hereinafter explained.

In such drawing, A denotes a closed case or vessel provided with aninduct, a, arranged as shown, or otherwise properly disposed. Withinsuch vessel is a hollow globular float, B, h. ving one or more openings,1), in its top or upper part. This float is fastened at its bottom toone end of a tubular arm, 0, which opens out of the globe float. At itsopposite end such arm is attached to and opens into the body part c of acommon water cock, D, having its stem d fastened to and extended throughthe lower part of the case A, in manner as shown. The said stem istubular or chambered, as represented at e, and is made cylindrical orslightly conical to receive the body part c, and to enable such to turnon the stem with a water-tight joint, there being in the stem arectangular opening, f, to correspond with or about with another suchopenening, g, in the body part, and leading into the hollow arm orconduit 0.

The object of the apparatus, like that of the other steam-traps, is toallow of the escape of water of condensation from a steam heating coilor vessel without at the same time admitting of the escape or loss ofsteam.

The operation of the apparatus may be thus explained: If we suppose thecoil or heater to be opened at its lower part into the caseA at itsinduct a, so that the water of condensation, as fast as formed, may flowfrom the coil or heater into the said vessel A, it will accummulatetherein so as to elevate the float B to the extent of its upward motion,after which it will flow over and into the said float, and

Brown, as shown in their expired patent of May 2, 1851, and make noclaim thereto, although there is a principle common to that and mysteam-trap, viz., the open float connected with the discharge-pipe, sothat the waste water will flow off through both. My construction andarrangement of parts prevents sediment from collecting in and cloggingthe float, or its educt, as it is liable to do in the patented trap.

In my arrangement the hollow arm 0 is entirely below the float B, anddisposed so that all sediment or deposits of any nature passing into thefloat, while it may be in action, will escape freely therefrom, withoutremaining in it and adding to its weight. g

In the trap of the expired patent, most of the float extends below thedischarge-pipe, and consequently it operates to collect and retainsedimentary matters, which, after a while, are liable to cover and chokethe eduction near the bottom of the float or the partition therein.

Consequently I make no claim to the principle common to the two traps,but confine my invention to my improvement or specific arrangement andconstruction of parts-that1s to say- W I claim--- The combination of theopen-top hollow float B with the tubular arm 0 andwastecock D, in thecase A, all constructed, an ranged, and to operate as shown andspecified.
